1 Claim. (Cl. 49-445) ABSTRACT OF THE DISCLOSURE The present invention relates to an improved window and window frame configuration.

In the past, windows and window frames have generally provided either a double hung configuration or a casement type window, each having certain window use limitations. The double hung window has always been a problem to safely clean, usually requiring dangerous outside-thewindow work in order to keep its panes fresh and clear. The casement window has been severely limited in that it is preferable to open outward so as not to obstruct the inside of a room. It is often also hard to reach the outer panes of such windows to clean them.

The casement window further, in its configuration, 'does not easily adapt to such uses including conventional screens. The swing of the easement requires some special form of adjustment to permit the window to be opened, accessible'to be opened and yet provide the normal inice mit the rod to rotate therethrough with a spring associated with each rod anchored at one end to the rod at a point internal of the housing and at its other end to the housing itself. The two parallel housings are themselves interengaged to prevent rotation of each housing against the tensions of the springs.

By providing a double hung set of Window frames with integral easements, the simplicity of the double hung window is available according to the present invention. The novel roller rods provides a simple mechanism for spring counterbalancing the window frames. The spring loading may be adapted to compensate for the weight of either metal or wooden frames allowing for freedom of movement up and down, notwithstanding the weight of the window frame itself.

Of particular importance is the integral casement adapted to swing inward into the room area. This inward swing avails both sides of the easement to be easily available for cleaning without having to lean out of the window and either window frame may be individually raised or lowered and the easement opened for ease and comfort in cleaning. Conventional screens may be used in conjunction with the window of the present invention since the easements open inward. The spring-loaded rollers in side by side horizontal configuration allow a space saving in frame size over sash counterweight windows which required two counterweights within the master window frame for each window section. Thus, the width of the master frame had to include provision for a sash weight for each window section, one on each side of the master frame, necessitating a wider master frame area.

While two supports for each window section of the present invention lead off the roller rods, the horizontal relationship of these rods is within the normal depth of the master frame configuration, saving space overall in the master frame size at least in its width without adding any height to the master frame, or without the addition tegrity of a screen. While screens are used with casement windows, they are usually complicated and expensive.

When window air conditioning units are desired, it is usually necessary to remove the easement or at least a pane so that the air conditioner can be installed.

Conventionally, both casement and double hung windows are most easily installed in building by the insertion of integral frames inclusive. of the windows or adapted to have the window portions easily installed in the window frames. Casement windows in particular are usually made of metal and as such may have heavier window frames than the conventional double hung window.

The double hung window is most easily adapted to use with conventional window screens and window air conditioners. The frames themselves are'usually of wood and are not as heavy as casement metal frames though of course in the usual configuration of double hung window weight is compensated for by the counterweight sash.

According to the present invention a double hung window with inwardly openable easements is provided counterbalanced by spring-loaded roller rods. The window frame construction generally comprises a frame channeled to guide the two window sections in parallel pairs with each window section having easements thereon adapted to open inwardly and window section support means for each window section with the window section support means located in the upper portion of the frame. The window section support means include two parallel aligned rods rotatably engaged in the frame with flexible supports extending from each rod, each rod suspending one of the window sections on such flexible supports. The rods each include a housing along part of its length adapted to perof any significant height over the conventional master frame height.

Although such novel feature or features believed to be characteristic of the invention are pointed out in the claims, the invention and the manner in which it may be carried out may be further understood by reference to the description following and the accompanying drawings.

FIG. 2 is a section of FIG. 1 at lines 22.

FIG. 3 is a plan view of the roller rods of the present invention.

FIG. 4 is a front elevation of a multipane casement embodiment of the present invention.

FIG. 5 is a cut-away detail view showing the construction of the frames and easements.

Referring now to the figures in greater detail, where like reference numbers denote like parts in the various figures.

As shown in the figures, a master frame 1 is provided with window sections 2, 3. Integral to each window section are the easements 4, 5. Each easement 4, 5 is provied with hinges 6 which are of any conventional construction. The hinges 6 may not extend outwardly beyond the clearance between the two window sections 2, 3 so that upward and downward movement is not impeded.

The easements 4, 5 are provided with inner peripheral flanges 7 against which the glass panes 8 are set in a conventional manner. The easements 4, 5 include an extending flange 9 which may be attached to the frames 10, 11 of the window section 2, 3. The details of connection at the frames 10, 11 are not shown though they may be welded, spot welded, screwed, clad or even made in an integral extrusion.

The master frame 1 may, for the purposes of ease of installation, be provided with a face plate 12 to frame the window as installed in building, the face plate 12 being jointed to the front flange 13 of the master frame 1 by means known in the art as heretofore set forth with regard to the joining of the easement 4, with the window frames 10, 11.

Integral to the master frame 1 are sliding channels 14, one on each side of the master frame 1 for each side of the sliding window section 2, 3. These channels 14 provide free guided movement of the window sections 2, 3 in a conventional manner.

The casement 4 as shown in FIG. 1 is provided with wing nut 15 screw fasteners which may lock into the window frame 10 at the opening 16. The casement 5 is provided with a screw fixture 17 as an optional means of fastening the easement. Such fittings might even be Dzus fittings or other optional closure means.

In FIG. 4 multipane easements 4, 5 are shown as alternate embodiments of the present invention.

The window sections 2, 3 are supported by ropes or cables 18 which run off spools 19. The spools are housed on rods 20 rotatably mounted in the upper section of the master frame 1. The rods are substantially aligned, each rotatably passing through a housing or cylinder 21. The cylinders 21 are mounted on the rods 20 by bushings 22, 23 which prevent the cylinders 21 from changing alignment on the rods.

Integral to the cylinders 21 are springs 24. One end of the springs 24 passes through the rod 20 or is attached thereto. The cylinders 21 are joined by a cross bar 26 which may be fastened to the cylinders 21 by screws 27 or other conventional fastening.

The bushings 22, 23 may be held by screws or other conventional means. The other end of the spring 24 passes through the cylinder 21 and is held from movement.

In operation the master frame 1 with the window sections 2, 3 is set up for use and may be installed as a unit in the course of construction. The cables 18 hang the window sections 2, 3, holding them in position. Normal upward and downward movement is effected in the conventional manner.

The rods 20, cylinders 21 and springs 24 counterbalance the weight of the window sections and support them in their selected positions.

A movement of a window 2, 3 section is transmitted from the cable 18 to the spools 19 causing the rod 20 to be rotated responsive to the tension of the spring 24. The spring 24 is either released in tension or tightened as the case may be, depending on the movement of the window sections 2, 3.

As the rod 20 rotates, lowering a window section 2, 3, the spring 24 is coiled together about the rod 20. This coiling exerts a pressure against the other end of the spring 24 which passes through the cylinder 21. Normally, the cylinder 21 would also tend to rotate under this spring tension but the cylinder 21 is restrained from movement by the crossbar 26. This effect is a mutual reaction with regard to both the rod 20 and cylinder 21 construction.

Initial spring tension must be adapted to take into account the position of upper and lower windows and have sufficient range of tensions to counterbalance the window sections 2, 3, yet not induce unwanted movement.

In cleaning, the casements 4, 5 are opened inward of the room, exposing both inner and outer surfaces for convenient cleaning. The wing nuts 15 or screws 17 lock the easements closed to maintain usual window closed integrity except when access is wanted for cleaning, changing glass or for other normal purposes. A

There is no access to the locking features of the casements 4, 5 from the outside portion so that the window sections 2, 3 are secure from unauthorized access.

It is of course realized that the cylinder 21 does not have to be in a cylindrical shape to perform its function and that the spools 19, bushings 22, 23 and crossbar 26 need not be screw fitted in order to serve their purpose as long as they are properly fastened.

The terms and expressions which are employed are used as terms of description; it is recognized, though, that various modifications are possible within the scope of the invention claimed.

Having thus described certain forms of the invention in some detail, what is claimed is:

1. A window frame construction comprising, a frame, a first window section, a second window section, each said window section including at least one inwardly openable casement section, first guide means in said frame adapted to guide said first window section, second guide means in said frame spaced apart from said first guide means adapted to guide said second window section, window section support means, said window section support means located in the upper portion of said window and including; a first rod rotatably engaged in said frame, a second rod rotatably engaged in said frame, a pair of fiexible supports extending from each of said rods to suspend each of said window sections, said first and second rods being in approximate parallel alignment, each said rod including a housing along part of its length adapted to permit said rod to rotate therethrough, a spr'ing associated with each said rod, one end of each said spring engaged in said rod within said housing and the other end of said spring engaged to said housing, means on said rod adapted to spatially align each said spring loaded housing on said rod, and means engageable between said housings adapted to prevent rotation of each said housing against the tensions of said springs.
